This invention relates t0 improvements in matrices and more particularly to matrices for a typographical machine and has for its object to provide matrices of the kind having a plurality of characters and adapted to permit of the section of a considerably greater number of diierent characters such as the Japanese or Chinese letters.

In the accompanying drawings:

Fig. 1 is a perspective view of a matrix embodying the invention.

Fig. 2 is a cross section of Fig. 1 on the line II-II.

Figs. 3, 4 and 5 illustrate several variations of the portion of the distributor teeth and lugs of the matrix in cross section on the corresponding line II-II in Fig. 1 by way of example.

Referring to the drawings, 1 represents the body of a matrix, which is substantially polygonal in its general outline and of suitable size and thickness. At the top of the matrix there is a V-shaped notch 2, and in this notch there are combinations of the distributing teeth 3.

y The matrix is reduced in thickness at the adjacent part 4 of the V-shaped notch, with or without lugs 5 for the selecting purpose in combination with the selecting teethprovided at the V-shaped notch. The location of the reduced portion and .the location, shape and size of the lugs must be of course dierent in different matrices for ditlerent characters, as shown in Figs. 2, 3, 4 and v5 by way ot example. The said reduction ot the adj acent part of the V-shaped notch will serve to assist to locate the centre of gravity of the matrix at its lower part, so that the matrix will turn to bring the V-shaped notch upwards when it is suspended on a rod.

Below the V-shaped notch the body is provided with a. central circular hole 6 in such a manner that the V-shaped notch merges into it so as to form an aperture ot about halt the diameter ot' it as shown in Fig. 1. The hole 6 serves to receive a bar (not shown) on which the matrix may be carried about and turned, and the lower selectin trackway ot a circular section (not shown xed to the bottom of the upper selecting trackway (not shown) engaging with the selecting teeth at the V-shaped notch to co-operate with the said reduced portion vand lugs provided at the adjacent part of the V-shaped notch upon selection. The matrix may be removed from the said bar through the aperture between the central hole 6 and the V-shaped notch, the bar consisting of two bar-members, each of a segmental section and a thickness of about a quarter of the diameter of the central hole 6, hinged at their lower edges with their opposing flat faces so as to be expanded or contracted in the said central hole by means of a wedging member (not shown).

rlhe characters 7 are indented on gonal faces of the matrix, which may be 15 to 2O in number. Between consecutive two characters the body is provided with projections 8 of suitable shape adapted to serve to engage with the automatic apparatus for dropping the matrix from the magazine by pressing the key, the turning means of the matrix for setting up the position of the character, the elevator screws, and for the guard of the matrix. Said projections may also be marked with the characters corresponding to the indented characters.

The matrix may be provided at one or both sides thereof with vertical grooves 9 for guide way engaging the guide of the channel leading to the magazine.

The above mentioned matrices are designed for use in my typographical machine for great many characters of dierent kinds, such as the the poly- 'Japanese or Chinese characters, thereby the typographical machine may be constructed in simple and compact form.

I do not wish that my invention is limited to the details of construction set forth, and variation and modication may be made within the spirit and scope of my invention.

Having now particularly described yand ascertained the nature of my said invention and in what manner the same is to be performed, I claim 1. A matrix for a typographical machine, including a body, which is substantially polygonal in its general outline and of suitable size and thickness, and provided with a number of characters of various kinds indented thereinto at the polygonal faces, and is formed With a top notch having distributor teeth and a central hole for receiving a distributor and elevator' bars and projections 5 positioned between every tWo consecutive indented characters substantially as described. 2. A matrix according to claim 1, in which the adjacent part of the top notch ismlled to reduce its thickness at one or both sides as and Jfor the purpose described. 8. A matrix including y'a polygonal body having a plurality of flat faces each provided with a dierent character-andalso having a circular central transverse hole and a V- shaped notch having selection teeth, said notch opening at the outer edge of the body and merging into the central hole at the bottom so as to form an aperture of about half the diameter of the central hole at its top, reduced portions and lugs for selection purposes cooperating With the 'selection teeth at the adjacent partof the V-shaped notch and a plurality of turning projections arranged alternately With respect to the characters. In testimony whereof I aix my signature.
